Influence of the honey Vrijes (Erica) on the elecrochemical behavior of tin in sodium chloride solution : bachelor thesis

Ispitivano je elektrokemijsko ponašanje kositra u 3 %-tnoj otopini NaCl, pH=3.0 pri temperaturi 25 o C bez i uz prisutnosti monoflornog meda Vrijes (erica). Mjerenja su provedena metodama linearne polarizacije i elektrokemijske impedancije spektroskopije. Određeni su korozijski kinetički parametri: nagibi katodnih i anodnih Tafelovih pravaca b k i b a, gustoće korozijske struje j kor , vrijednosti korozijskih potencijala E kor i polarizacijski otpor R p . Uspoređeni su rezultati dobiveni korištenim metodama. U ispitivanom koncentracijskom području med VrijThe electrochemical behavior of tin in 3% NaCl solution, pH = 3.0 at 25 o C without and in the presence of monochlorine honey Vrijes (erica) was investigated. The measurements were performed by linear polarization and electrochemical impedance spectroscopy methods. The corrosion kinetic parameters were determined: the slope of the cathode and anode Tafel directions b k and b a , the corrosion current density j kor , the values of the corrosion potentials of E kor and the polarization resistance R p . The results obtained by the methods used were compared. In the tested concentration range, honey Vrijes (erica) cannot be successfully used as a tin corrosion inhibitor in 3% NaCl solution, pH = 3.0
